CKD and hypertension during long-term follow-up in children and adolescents previously treated with extracorporeal membrane oxygenation.

ABSTRACT:

Background and objectives

Many children receiving extracorporeal membrane oxygenation develop AKI. If AKI leads to permanent nephron loss, it may increase the risk of developing CKD. The prevalence of CKD and hypertension and its predictive factors during long-term follow-up of children and adolescents previously treated with neonatal extracorporeal membrane oxygenation were determined.

Design, setting, participants, & measurements

Between November of 2010 and February of 2014, neonatal survivors of extracorporeal membrane oxygenation who visited the prospective follow-up program at 1, 2, 5, 8, 12, and 18 years of age were screened for CKD and hypertension (BP?95th percentile of reference values). CKD was suspected in children with either an eGFR<90 ml/min per 1.73 m(2) or proteinuria (urinary protein-to-creatinine ratio >0.50 for children ages ?24 months and >0.20 at >24 months). The RIFLE classification (risk, injury, or failure as 150%, 200%, or 300% of serum creatinine reference values) was used to define AKI during extracorporeal membrane oxygenation without preemptive hemofiltration.

Results

Median follow-up of 169 screened participants was 8.2 years (interquartile range=5.2-12.1 years). Nine children had a lower eGFR, but all rates were >60 ml/min per 1.73 m(2). Proteinuria was observed in 20 children (median=0.26 mg protein/mg creatinine; interquartile range=0.23-0.32 mg protein/mg creatinine), and 32 children had hypertension. Only history of AKI was associated with CKD (P=0.004). Children with RIFLE scores injury and failure had 4.3 times higher odds of CKD signs or hypertension than those without AKI (95% confidence interval, 1.6 to 12.1; P=0.004).

Conclusions

Altogether, 54 participants (32%) had at least one sign of CKD and/or hypertension. However, most values were marginally abnormal, with no immediate consequences for clinical care. Nevertheless, a prevalence of 32% clearly indicates that survivors of neonatal extracorporeal membrane oxygenation, especially those with AKI, are at risk of a more rapid decline of kidney function with increasing age. Therefore, screening for CKD development in adulthood is recommended.

Project description:Extracorporeal membrane oxygenation is a potentially life-saving intervention in refractory cardiopulmonary failure, but it requires anticoagulation to prevent circuit thromboses, which exposes the patient to hemorrhagic complications. Heparin has traditionally been the anticoagulant of choice, but the direct thrombin inhibitor bivalirudin is routinely used in cases of heparin-induced thrombocytopenia and has been suggested as a superior choice. We sought to examine the timing of hemorrhagic and thrombotic complications after extracorporeal membrane oxygenation cannulation and to compare the rates of such complications between patients anticoagulated with heparin versus bivalirudin.DesignRetrospective cohort study.SettingJohns Hopkins Hospital patients between January 2016 and July 2019.PatientsAdult (> 18 yr) extracorporeal membrane oxygenation patients.InterventionsPatients were anticoagulated either with heparin or bivalirudin.Measurements and main resultsWe compared rates of hemorrhagic and thrombotic complications by time on heparin versus bivalirudin and characterized the average time to each complication. Of 144 extracorporeal membrane oxygenation patients (mean age 55.3 yr; 58% male), 41% were on central venoarterial extracorporeal membrane oxygenation, 40% on peripheral venoarterial extracorporeal membrane oxygenation, and 19% on venovenous extracorporeal membrane oxygenation. Thirteen patients (9%) received bivalirudin during their extracorporeal membrane oxygenation run, due to concern for (n = 8) or diagnosis of (n = 4) heparin-induced thrombocytopenia or for heparin resistance (n = 1). The rate of hemorrhagic or thrombotic complications did not differ between heparin (0.13/d) and bivalirudin (0.06/d; p = 0.633), but patients on bivalirudin received significantly fewer blood transfusions (1.0 U of RBCs/d vs 2.9/d on heparin; p < 0.001).ConclusionsOur results confirm the safety and efficacy of bivalirudin as an alternative anticoagulant in extracorporeal membrane oxygenation and suggest a potential benefit in less blood product transfusion, although prospective studies are needed to evaluate the true effect of bivalirudin versus the disease processes that prompted its use in our study population.

Project description:BackgroundWe tested the effect of different blood flow levels in the extracorporeal circuit on the measurements of cardiac stroke volume (SV), global end-diastolic volume index (GEDVI) and extravascular lung water index derived from transpulmonary thermodilution (TPTD) in 20 patients with severe acute respiratory distress syndrome (ARDS) treated with veno-venous extracorporeal membrane oxygenation (ECMO).MethodsComparative SV measurements with transesophageal echocardiography and TPTD were performed at least 5 times during the treatment of the patients. The data were interpreted with a Bland-Altman analysis corrected for repeated measurements. The interchangeability between both measurement modalities was calculated and the effects of extracorporeal blood flow on SV measurements with TPTD was analysed with a linear mixed effect model. GEDVI and EVLWI measurements were performed immediately before the termination of the ECMO therapy at a blood flow of 6 l/min, 4 l/min and 2 l/min and after the disconnection of the circuit in 7 patients.Results170 pairs of comparative SV measurements were analysed. Average difference between the two modalities (bias) was 0.28 ml with an upper level of agreement of 40 ml and a lower level of agreement of -39 ml within a 95% confidence interval and an overall interchangeability rate between TPTD and Echo of 64%. ECMO blood flow did not influence the mean bias between Echo and TPTD (0.03 ml per l/min of ECMO blood flow; p = 0.992; CI - 6.74 to 6.81). GEDVI measurement was not significantly influenced by the blood flow in the ECMO circuit, whereas EVLWI differed at a blood flow of 6 l/min compared to no ECMO flow (25.9 ± 10.1 vs. 11.0 ± 4.2 ml/kg, p = 0.0035).ConclusionsIrrespectively of an established ECMO therapy, comparative SV measurements with Echo and TPTD are not interchangeable. Such caveats also apply to the interpretation of EVLWI, especially with a high blood flow in the extracorporeal circulation. In such situations, the clinician should rely on other methods of evaluation of the amount of lung oedema with the haemodynamic situation, vasopressor support and cumulative fluid balance in mind.Trial registrationGerman Clinical Trials Register (DRKS00021050).
